人类老化是现在最引人注目的问题.一、老化与卵巢1.卵巢的重量与体积:卵巢重量在20岁代形成峰值,而后渐减,40、50岁代重量明显下降,60岁代不足20岁代的1/2.卵巢重量越减少血中雌二醇越低下,所以在40～50岁代的更年期就出现明显的激素失调症状.即由于分泌类固醇的成熟卵泡减少而影响激素的分泌,这与卵巢重量减少有很大关系.另外卵巢的重量虽有很大个体差异,但可直接反映卵巢机能.卵巢体积与卵巢重量变化一样,20岁代卵巢最大,30岁代明显下降,40岁代不足峰值的1/3.
Aging and ovarian 1. Ovarian weight and volume: ovarian weight in the 20-year-old peak, and then decreased, 40,50-year-old weight decreased significantly, less than 60 years of age 20-year-old 1 / 2. Ovarian weight decreased the lower the blood estradiol, so in 40 to 50 years of menopause obvious symptoms of hormone imbalance that is due to the secretion of steroid mature follicles affect the secretion of hormone secretion , Which has a great relationship with the reduction of ovarian weight.In addition, the weight of ovary, although a very large individual differences, but can directly reflect the ovarian function.While ovarian volume and ovarian weight changes, 20-year-old ovary largest, 30 years decreased significantly, 40 One-third less than the peak of the age.
